Watt

Watt (W) is a unit of power. Power is the rate of energy usage per time unit. One watt (W) is equal zu one joule (J) per second (S).

Ampere

Ampere (A) is a unit of elektrischer Strom. Electric current is the rate of electric charge flow per time unit. One ampere (A) is equal zu one coulomb (Q) per second (s).

DC watts zu amps calculation

Der Strom I in Ampere (A) is equal zu the power P in Watt (W), divided by the voltage V in Volt (V):

I(A) =
P(W)V(V)

Beispiel

P = 200W, V = 40V

I =
200W40V
= 5A

AC single phase watts zu amps calculation

Der Phasenstrom I in Ampere (A) is equal zu the power P in Watt (W), divided by the power faczur LF multipliziert mit der RMS-Spannung V in Volt (V):

I(A) =
P(W)LF × V(V)

The power faczur of resistive impedance load is equal to 1.

Beispiel

P = 2000W, V = 110V, LF = 0,8

I =
2000W0,8×110V
= 22,72727A

AC three phase watts zu amps calculation

Calculation with line zu line voltage

Der Phasenstrom I in Ampere (A) is equal zu the power P in Watt (W), divided by square root of 3 times the power faczur LF times the line zu line RMS voltage VL-L in Volt (V):

I(A) =
P(W)3 × LF × VL-L(V)

The power faczur of resistive impedance load is equal to 1.

Calculation with line zu neutral voltage

Der Phasenstrom I in Ampere (A) is equal zu the power P in Watt (W), divided by 3 times the power faczur LF times the line zu neutral RMS voltage VL-N in Volt (V):

I(A) =
P(W)3 × LF × VL-N(V)

The power faczur of resistive impedance load is equal to 1.

Typical power faczur values

Do not use typical power faczur values for accurate calculations.
